'CARTON SETUP momma:

Patented May 26, 1953 CAR-TON SETUP MACHINE Richard J. Fahey, Evanston, 111., aseignor to Shellmar Products Corporation, Chicago, 111., a corporation of Delaware Application September as, 1946, Serial No. 699,950

This invention pertains to automatic set-up machines for collapsed egg cartons, particularly cartons of the type disclosed in U. S. Reissue Patent No. 18,922 to Felix Troyk, a type which has met with considerable commercial success.-

Automatic carton set-up machines for cartons of the type indicated above have been heretofore provided, however, they are ordinarilyheavy and cumbersome and include parts which are expensive to fabricate. Moreover, they are in many cases subject to frequent delays in operation and at best operate at relatively low speed.

It is an object of this invention to improve on prior automatic carton set-up devices by providing a machine which is light in weight and easily handled; which is composed of relatively inexpensive parts; which passes the carton through a straight line course of advance in the set up operation, during all of which the carton is held and supported against displacement apt to cause the carton to become mangled or broken; which has a tendency to discharge any carton that for any reason has not properly setup during passage through the machine; and which is capable of operation at extremely high speeds.

A further and more specific object of the invention is the provision of a machine utilizing chute means for forming the carton body and orbitally traveling elements operating transversely of said chute means to cause engagement of certain transverse partitions and the bottom portion of a carton of the type identified above.

Still other and further objects and advantages will appear from the following description and from the drawings in which:

Fig. 16 is a fragmentary perspective showing the blade of Fig. 13 in its most extended position in relation to a carton after rotative erection of the transverse partitions thereof by the mechanism of Fig. 11.

The Troyk type carton, which is seen on the drawings in Figs. 8, 15 and 16, is of unitary paperboard construction and consists of a cover panel having on its front margin a locking strip provided with integral locking hooks: rear wall panel; a relatively wide panel, forming a longitudinal partition and bottom in the set-up carton; a front wall panel having a plurality of substantially triangular extensions (see Fig. 16); a. transverse partition panel comprising a plurality of individually cut-out transverse partitions; and an attaching or glue strip which is adhesively attached to the inner side of the rear wal nanel. The severe! nanels. are oldable with 3 respect to each other along transverse fold or score lines.

In the collapsed condition of the carton shown in Fig. 8, the component parts thereof are so disposed as to present a single paperboard thickness at the cover portion, a double thickness at the side opposite the cover and triple thickness medially of the carton.

To set-up the carton from this knocked-down shape, the front and rear wall panels are pressed into generally upright position, the transverse partitions are swung on integral hinges from coplanar knock-down position to spaced parellel position, and the longitudinal partition and bottom forming panel brought from an outwardly extending to an inwardly extending position to interlock with the ends of the transverse partitions. To this end, the latter are medially bifurcated and have opposed hooks formed thereon, and the longitudinal partitions have openings to receive the hooks and lower medial portions of each of the transverse partitions.

Referring to the drawings, the reference numeral I indicates the fiat bed of the machine which is positioned in a frame 2 supported upon pairs of opposed fore, intermediate'and back legs 3, 4, respectively, which are of different length. An electric motor 6 is positioned on a shelf I supported by legs 3 and 4, its pulley 9 carrying V-belt 9. Belt 9 is in driving engagement with a driven pulley III Journalled on frame 2 to impart the required movements to the machine, as hereinafter described.

At one end of the machine bed I, which will hereinafter be referred to as the rearward part I,

of the apparatus, is a hopper or magazine II formed by four upwardly directed angle iron corner posts fastened to the machine bed. Numerals I2, I3 indicate the rearward pair of posts and numerals I4, I5 indicate the forward pair thereof. Corner posts I2, I3, I4, I5 are spaced both longitudinally and transversely of the bed I to accommodate and retain at the corners a stack of collapsed cartons of the type mentioned hereinabove, typically indicated in the drawings by number I6. The cartons are preferably placed in the magazine with their folded transverse partitions extending rearwardly of the machine, as shown in Fig. 8. Parallel friction reducing strips I1 are positioned on bed I, within the lateral confines of magazine II, to facilitate feed of cartons I6 therefrom.

Machine bed I has a longitudinally extending center slot I8 cut therethrough within the confines of the magazine to permit extension therethrough of the integral drive bar I9 of a reciprocating dog 20 (see Fig. 1). Dog 20 has an abrupt vertical fore-edge 2| for engagement with the sides of each bottommost carton in the stack to advance them in the machine, in the forward movement of the dog, and has a rearwardly slanted top and rear portion 22, whereby to avoid tearing the lowermost carton in the stack in its rearward movement. It will be noted by reference to Fig. 8 that dog 20 engages each lowermost carton at the triple thickness medial portion thereof. The top of the dog is below the top surface of this portion, and is thus engageable only with the lowermost carton on the forward stroke and incapable of advancing for set-up more than one carton at a time. Below bed I, drive bar I9 is carried in fore and aft guides 23, 24, respectively. Medially of the guides the bar carries a connecting member 25, to which is attached one end of a pitman 26, the other end 01 '4 pitman 26 being eccentrically pivoted to a rotatable gear 21, particularly shown in Figs. 1 and 4. Rotation of gear in a manner to be described results in reciprocation'of the pitman and dog 20 to effect initial forward advance of the lowermost carton from magazine II.

Referring now to @ig. 4, it will be noted that gear 21 is mounted on a stub shaft 23, carried on a bracket 29 depending from bed I. A similar bracket 35 depends from the bed in transversely opposed, parallel relation to bracket 29 and a lower shaft 3| mounted transversely between said brackets serves as a support for a pinion 32 which drives gear 21. Shaft 3| also carries a chain sprocket 33 in spaced relation to pinion 32, the function of which will be later described.

Above gear 21 and meshed therewith to be driven thereby, is a gear 34 which is fixedly attached to a shaft 35, the latter being borne in spaced opposed bearings 36, 31 on the machine bed. A carton body biasing or elevating element, in the form of a wheel 39, is mounted substantially medially of shaft 35 to extend upwardly thru an opening 39 in said machine bed. At one side of wheel 38 and in vertical alignment with sprocket 33, is a further chain sprocket 40, said sprockets serving to guide certain chain operated feed means, as will be more fully set forth hereinafter. Feed rollers, designated H, 42, respectively, are also borne by shaft 35 in spaced relation to one another. These rollers extend upwardly above the level of machine bed I through openings 43, 44, respectively, provided in such bed. In order to drive the upper feed rollers 56 and 5I positively, a gear 45 is mounted fixedly on one end of shaft 35 in driving engagement with another gear 46 which is fixedly attached to a shaft 41 borne by spaced adjustable bearing blocks 45, 49 which are mounted on the respective magazine corner posts I4, I5. Also fixedly mounted on shaft 41 are a pair of knurled, upper carton feed rollers 50, 5| which are in respective vertical alignment with lower carton feed rollers H, 42, coacting with the latter in advancing the lowermost carton from the magazine, as will be described. The drive of shaft 35 from gear 21 results in driving shaft 41 at equal speed whereby positive feeding action is imparted to rollers 55, 4| and 5|, 42.

A transverse plate 52 is secured to corner posts I4, I5 at a point rearwardly of and slightly above shaft 41 and carton stops 53, 54, depend therefrom to a point near bed I, the purpose of said stops being to restrict the outlet of magazine II and prevent ejection of more than a single carton at a time.

Bearing blocks 48, 49 are intended to have limited upward sliding displacement on corner posts I4, I5 and for that purpose are provided with integral upwardly extending slide portions 55, in which are formed vertically extending slots 56.

Antifriction cover plates 51, secured by studs 53 to the posts I4, I5 coact with said posts in defining shielded slideways for the slide portions 55 which permit limited vertical movement of bearings 46, 49. In order to determine and adjust the lowermost position of the bearings, pins 59, 50 are mounted on the comer posts within slots 56 as particularly shown in Figs. 4 and 5. Slide portions 55 are threaded to receive adjustable set screws 6I, 62 which abut. pins 59, 66, these set screws GI, 62, being locked in desired position by lock nuts 63, 64. Screws 6|, 62 are of such a length as to serve as centering means for one end of the coil compression springs 85, 68, and said springs at their other end abut the flange of an angle iron support 81 mounted transversely of corner posts I4, I5. Said support carries downwardly extending lugs 88, 69 on which the adjacent ends of the coil springs are centered to hold them against displacement.

As mentioned hereinabove a carton of the Troyk type, when folded, presents along its one edge a double thickness of paperboard and along its cover it presents but a single thickness, usually about .023 inch per sheet. Since it, is important that both upper and lower pairs of carton feed rollers 50, and 4|, 42 respectively, have firm frictional engagement with the carton during the advance thereof, it has been found desirable to bias the position of shafts 35, 41 at an angle. Thus feed'rollers 4 I, 50 are enabled to contact the carton along a part thereof having a double thickness with the same compressive orce as feed rollers 42, 5| contacting the carton along the cover, where there is but a single thickness of material. The necessarily biased relation of the opposed shafts and affixed rollers can be effected to some degree by the inherent spring loaded, floating character of bearings 48, 49, but best results have been obtained by actually biasing shafts 35, 41 mechanically so that rollers 4|, 50 have somewhat more than twice the gap present between rollers 42, 5|. Specifically, best results have been obtained by permitting a normal opening of about .0125 inch between rollers 4|, 58 as contrasted to a normal opening of .005 inch between rollers 42, 5|. This adjustment is readily effected by manipulation of set screws 6|, 82

As particularly shown in Fig. 2, a central slot.

10 extends longitudinally of machine bed I throughout the length of such bed, forwardly of wheel opening 39, with which such slot 10 merges. A pair of longitudinally spaced, aligned chain supports or guides, are disposed medially of slot 18, in alignment with the above mentioned sprocket 40 and with a drive sprocket 1| at the forward end of the machine, the rearmost of said guides being designated 12, and the forward designated 13. (See Fig. 3.) Said guides are mounted on side spacers 14 and are positioned below the level of machine bed I a distance to permit the roller chain 15 referred to above to travel below machine bed I, out of contact with cartons thereon. Chain 15 carries lugs 16, at regularly spaced intervals, which project through slot 19 into engagement with the rear of a folded carton to advance the same along the bed.

As shown on the drawings, guides 12, 13 are spaced apart longitudinally at a point about medially of the machine. At its forwardmost end, guide 12 has a downward sloping chain support surface 11, terminating in an abruptly rounded end as at 18, whereby to permit chain carried lugs 16 to first gradually withdraw from pushing contact with cartons advanced thereby, then, after disengagement from the cartons, to drop abruptly. Chain 15 then passes around an idler sprocket 19 on a shaft I19, shown in Figs. 13 and 14, thence returns into engagement with the carton as each lug 19 whips around the relatively abruptly curved inner end 88 of guide 13. As shown in Figs. 1 and 3, after passing around forward drive sprocket 1|, chain 15 passes around an idler sprocket 8|, thence travels substantially horizontally around sprocket 33 and upwardly over sprocket 48. Chain 15 is driven at sprocket 1| in the manner hereinafter described, and in its movement transmits power through sprockets 33 6 and 48 to the mechanism shown in Fig. 4, to drive the feed shafts 35, 41.

As shown in Figs. 2, 12, 15 and 16, a carton cover restraining plate 82 having an upturned fore-lip 83 extends throughout the length of the machine, at one side thereof, from a position forwardly of the carton feed rollers 50, 4| and 5|, 42 to the discharge end of the machine Plate 82 is disposed at a slight elevation above machine bed I and parallel thereto, providing a continuous longitudinal pocket 84, which holds down the covers of cartons in their progress through the machine. If desired, as shown in Fig. 1, both the machine bed I and the plate 82 may be provided with openings 85, 88, respectively, preferably in ofi'set relation, to permit easy removal from pocket 84 of accumulated dust, dirt, carton pieces, etc.

Referring particularly to Figs. 1, 2 and 3 it will be noted that the carton forming chute or channel of the machine employs a pair of carton body shaping chute members, that which operates on the transverse carton partition panel being designated 81 and that which operates upon the bottom and longitudinal partition portion of the cartons being designated 88. As also shown in Figs. 1 and 8, chute member 81 has a pointed end 89 which extends adjacent the carton feed rollers 42, 5|, at about the level of cover retaining plate 82. Accordingly, when a carton is fed out through the feed rollers, the slight upward bend imparted to it by biasing roller 38 tends to open up a space between the carton cover and the folded transverse partitions into which the pointed end 89 enters. Thus the carton body shaping operation is initiated.

Chute point 89, in preferred form, extends closer to the carton feed rollers than does the corresponding end 90 of chute 88, so that the carton will have progressed forwardly a distance in contact with chute 81 before entering chute 88. The lower wing of the U-shaped open end 98 of chute 88 is at about the level of machine bed I and to accomplish this object the bed is recessed as at 9|. (See Fig. 8.) The positioning of chutes 81, 88 is critical, hence adjustment means, particularly shown in Fig. 8, are provided for adjustment of both the vertical and horizontal positions of such chutes. The adjustment means for chute 81 comprises a bowed strap 92, having its one end rigidly attached to an outwardly curved lower portion of chute 81 and having a longitudinal slot 93 formed adjacent its outer downwardly bent end. A stud or bolt 94 connects strap 92 to the machine bed, through plate 82. Hence lateral adjustment of the chute may be effected. Medially of its length, strap 92 has an adjustment screw 95 threaded therein, which abuts a thrust member on plate 82. A lock nut 98 permits looking of screw 95 in desired position to adjust the vertical disposition of chute 81.

The positioning of chute 88 is not as critical to the extent of the other chute, since at its end 98 it is relatively open. Primarily to provide lateral adjustment of chute 88 an adjustment strap 91 is fastened thereto and such strap has a longitudinally extending slot 98 formed therein. A stud bolt 99 passes through slot 98 to fasten strap 91 to machine bed I. Sideways adjustment of chute 88 is thus permitted by varying the relation of the last named strap and bolt.

The chutes 81, 88 converge with respect to one another (see Fig. 2) as they progress away from magazine II and their respective sectional conformations change progressively. The change in angularity of chute 81 from its end point 89, to a position of greatest approach to the vertical is shown by the series of cross sections shown in Fig. 10, taken at successive points a through 9 of Figs. 1 and 3. The corresponding change in conformation of chute 58 from its end 50 is generally indicated by he correspo n ries cross sections shown in Fig. 9.

Chutes 51, merge, about medially of the distance between the forward end of the magazine and the other end of the machine, with a further, generally rectangular chute, indicated generally by numeral I00. The latter, adjacent the point of merger of chutes 01, as therewith, has an upturned, longitudinally directed, carton guiding forelip IOI integral with the chute top I02, and said chute top I02 has a longitudinally extending, inwardly bent or re-entrant side lip I03 adapted, as shown in Fig. 15, to engage and restrain the triangular projections on the top of the carton front wall. Chute I00 is otherwise open along its side adjacent said lip I03 to permit entry thereinto of the transverse partition depressing or erecting head I00, to be described. As will be seen from Figs. 12, 15 and 16, chute I00 has an upper sidewall I04 opposite lip I03 which has a slightly outwardly curved, convex portion I05 at its connection to top I02, opposite the in-tumed side lip I03. The corresponding lower side portion of chute I 00 consists of a lower wall I05 held in spaced relation to upper wall I04 by a U-shaped support member I01 (see Fig. 12). This provides a longitudinally directed slot I00 between walls I04, I06 in which the carton bottom and longitudinal partion inserting blade I14, hereinafter described, may perform its function, the lip I03 meanwhile guiding and restraining the carton body at its opposite top side.

The transverse partition depressing and erecting head I09, shown in Fig. 11, is disposed on the side of the carton opposite blade I14, and comprises a generally rectangular base carrying two rows of spaced, fixed partition depressing fingers, each indicated by the numeral II 0. Adjacent each opposed pair of fingers is mounted a partially rotatable, bifurcated leaf member III pivoted by a transverse shaft II2 on the head I05. Each leaf member III has a rearwardly extending actuating foot I I3 formed thereon and in turn pivoted to a connecting bar II4, the latter being adapted for movement longitudinally of head I03 and in such movement imparting partial rotation to all leaf members III in the series.

Head I09 is rigidly attached to an orbitally movable carrier II5 which has a pair of depending cylindrical sleeves I I5, Ill in pivotal engagement with the respective eccentric studs H8, H5 on spaced gears I20, I2I. Gears I20, I2I rotate on stub shafts I22, I23 respectively suitably mounted in frame 2, and are driven in a common counter-clockwise direction by a single drive pinion I24, located between and meshing with said gears. Hence upon rotation of said pinion and gears, carrier I I5 and head I09 are caused to move in an orbital path, accompanied by movement of the leaf members III and certain other thereon which contacts the end of actuating arm I23. This in turn imparts movement to said arm and its interconnected, above-described parts including bar II4, closing leaf members II I during reciprocation of plate I35. Said leaf members are closed against the resistance of a coil tension spring I31 which tends to return leaves III to normally open position.

Plate I35 has a pair of identical cam surfaces I33, I35, formed on the rear side thereof which are maintained in constant contact with the aforesaid eccentric sleeves II 5, H1 in the reciprocation of the plate and pivoted at each end of plate I35 are a pair of identical arms I40, I4\I. These arms are fixedly mounted on shafts I42, I 43 respectively which extend below machine bed I being carried in sleeve bearings I44, I45. Below the level of machine bed I shaft I42 is secured to an arm I45, to the end of which is attached a coil tension spring I41, the other end of said spring being attached to the machine frame 2. The purpose of spring I41 is to urge plate I35 in a direction to maintain cam surfaces I33, I35 in constant contact with eccentric sleeves H5, H1. Furthermore, to insure shock-free return of plate I35 under the tension of spring I41, said plate is provided with a cam extension surface I40 merged into the cam surface I38 which reduces slap during return.

Mounted on the other depending shaft I43, below the level of machine bed I, is an arm or lever I40, to which is pivotally attached a diagonally extending rod I50. As shown in Figs. 11 and 13, rod I'50 transmits movement in a diagonally forward direction to an arm I5I positioned in the same plane as and parallel to arm I40. Arm I5I is fixedly attached to an upwardly extending rock shaft I52 which is pivotally mounted on the machine bed by a sleeve bearing I53. Another arm I54 is attached to the upper end of rock shaft I52, above the level of machine bed I.

Sleeve I53 also functions as a pivotal support, above the level of machine bed I, for a bell crank member I55 which operates in tandem with a second similar bell crank I50 on a shaft I55.

Like shaft I52, shaft I55 has a bearing paralleling shaft I52 within a sleeve I'51, being retained within such sleeve by a collar I58. An arm I55 similar to arm I54 is fixedly connected to shaft I55 in coplanar and generally parallel relation to arm I 54. The second bell crank I50 is secured to sleeve I51 in coplanar relation to crank I55. The long arms I5I, I52, respectively of said cranks are aligned with one another but extend in opposite directions and the short arms I53, I54 of the bell cranks are pivotally connected by a diagonal link I55 whereby the cranks I55, I60 have equal and opposite rotative movement when one thereof is oscillated. Arms I54, I55 have identical headed retaining guides I55, I51 on their extremities, the necks of which approximate the width of parallel slots I58, I55 in a blade I14, through which they extend. Bell crank arms I 5I, I52 also have headed retaining guides I10, I1I similar to guides I65, I51, the necks of such guides approximating the width of spaced, aligned slots I12, I13 in blade I14. The circular openings shown in blade I 14, and to which no numerals have been applied, are formed therein 9 only for the purpose of reducing weight of such blade. Along its inner edge blade I14 has a series of identical notches I15 formed therein to bridge th transverse partitions of the carton in engaging the bottom thereof in the manner shown in Figs. 15 and 16.

Again referring to Fig. 13, a swingable coupling element I18 is pivoted to hell crank arm I63 and also to a pin on one end of an arcuate actuating arm I11. The other end of arm I11 is attached to a rocker arm I18 attached to a shaft I19, which is rotatably mounted parallel to machine bed I in parallel brackets I88, I 8|. Accordingly rotation of shaft I19 results in reciprocation of actuating arm I11, accompanied by oscillation of bell cranks I55, I68 in opposite directions. Such rotation is accomplished through a one revolution frictional slip clutch, in the followin manner. I

A steel clutch plate I82 having an outwardly extending trip lug I83 mounted on its exterior surface is pinned to shaft I19 and is engageable on its opposite surface in frictional contact with a fibre clutch disk I84. Disk I84 and sprocket 19 are preferably integrally connected and are mounted on shaft I19 for relative rotation thereon, slipping relative to plate I82 when the same is restrained from rotation and at other times driving said plate. As particularly shown in Fig. 12, sprocket 19 bears axially against the smooth flat side of an anti-friction thrust washer I85, which in turn abuts the inner side of bracket I8 I. On the opposite side of bracket I8I is a boss I86 provided with an annular shoulder I81 against which one end of a coil compression spring I88 abuts. The other end of spring I88 abuts supporting collar I89 formed of soft metal, and the latter is in face abutment with the hardened race I98 of a ball bearing thrust assembly I9I ineluding race I92. Shaft I19 is threaded at its end, as at I93, to receive a spring tension adjusting nut I94. Hence the degree of slip-driving frictional engagement of the clutch plate I82 and disk I84 is accurately adjusted.

As shown in Figs. 12 and 14, a rock shaft I95 is mounted between brackets I88, I8I rearwardly of and above rotatable shaft I19. A hook I96 is mounted on shaft I95 in alignment with clutch lug I83, being kept in restraining relation to such lug under the tension of a helical spring I91, one end of which is attached to said hook and the other end of which is attached to a suitable point on the machine body. Also fixedly mounted on rock shaft I95. in spaced relation to hook I 96 and adjacent the side edge of chain 15, is a detent lever I98 which is contacted by the forward edge of each chain carried carton advancing lug 16 in its path of travel. When contacted by lug 16 lever I98 is swung backwardly, carrying with it shaft I95 and hook I96, against the tension of spring I91, thus temporarily disengaging the hook I98 from lug I83, as shown by the dotted lines in Fig. 14, and permitting rotation of clutch plate .I82 and shaft I19 by disk I84.

As previously described, motor 6 transmits motion through belt 9 to pulley I8. As shown in Fig. 12, pulley I8 is attached for rotation to a transverse shaft I99 journalled in the machine frame 2. Approximately intermediate the length of shaft I99 a sprocket 288 is secured, rotation of which transmits movement through chain 28I to a sprocket 282 fixedly mounted on a parallel rotatable shaft 283 at the forepart of the machine. Shaft 283 also carries sprocket 1| which actuates carton advancing chain 15.

As shown in Figs. 11 and 12, a vertically extending bevel gear 284 is secured on the end of shaft I99 opposite pulley I8, which is meshed with a similar gear 285 mounted on rotatable vertical shaft 286. Drive pinion I24 is secured to theother end of shaft 286, so that the partition erecting head and parts associated therewith obtain their drive in this manner.

Rotative movement imparted shaft I99 by motor 6, through the belt and pulley assembly shown, is transmitted through chain 28| and its associated sprocket to shaft 283, rotating sprocket 1| to drive chain 15. Chain 15 passes around adjustable idler 8| and drives sprockets 33 and 48 (see Fig. 4), the movement of these last named sprockets being transmitted through the gear train comprising pinion 32 and gears 21, 34 to drive pitman 28 and reciprocate dog 28.

In operation with a stack of cartons disposed in magazine I| dog 28 shifts forwardly until its abrupt upright edge 2| comes in contact with the rear end of the bottommost carton at a position behind the triple thickness folded transverse partitions and feeds the same forward in the direction of opposed carton feed rollers 4|, 58 and 42, 5 I. Once the carton has begun to pass through the relatively narrow opening between machine bed I and stop elements 53', 54 its forward end becomes engaged between the aforementioned rollers. The speed of said rollers is such that the carton is accelerated and in consequence is withdrawn from contact with dog 28, which thereupon returns to original position.

Coincident with its entry between the bight of the feed rollers mentioned above, the carton is medially biased upwardly by roller 38, which biasing tends to elevate the end transverse partitions slightly from their fiat, generally parallel position with respect to the carton cover. This permits insertion of the end 89 of chute 81 into the space between the partitions and cover, as particularly shown in Fig. 8.

As will be noted from Fig. 1, the arcuate or U- shaped end portion of chute 81, forwardly of chute point 89, extends in the rearward direction to an extent such that the operation of elevating the transverse partition above the carton top begins prior to entry of the folded bottom and longitudinal partition portion in chute 88. However, once the last named carton portion has entered chute 88 the carton area adjacent the line of bottom fold tends to engage the internal apex of the angled chute 88. Thus, continuous, opposed abutment surfaces are provided to receive the oppositely directed forces placed upon the carton as the same is forced between the converging chutes 81, 88. As chutes 81, 88 converge, their surfaces approach the vertical as shownin Figs. 9 and 10, and impart a rectangular outline to the carton body, other than the cover. When the carton has been advanced slightly to extend forwardly of the feed rollers, the carton cover follows the plane surface of machine bed I between the bed and plate 82 and continues in the pocket 84 throughout its travel through the machine. If for any reason the carton cover is slightly elevated as it emerges from magazine II, it is guided into recess 84 by the upturned forward lip 83 of plate 82.

As soon as the rearward edge of the carton has passed out of contact with rollers 4I, 58 and 42, 5| the carton is engaged and forwarded by a lug 18 carried by the chain 15, said lug coming into contact with the carton rear immediately below the still collapsed, rearwardly extending '11 transverse partitions. So propelled, the carton advances into the forward portion I of the chute, in which the operation of erecting and locking the carton partitions is performed.

The timing of the parts is such that at about the time lug I8 begins its withdrawing action over inclined surface TI on guide I2, to pass around sprocket I8, the partition depressing head I08 and associated mechanism particularly shown in Fig. 11 begins its inward stroke into the opening below chute side restraining lip I03. At this moment the fixed fingers I I0 are in register with the carton transverse partitions, the points thereof entering the carton interior immediately forwardly of each partition and its hinge line, i. e., on the side of the partition toward which it is to be swung to erected position. Substantially coincident with this engagement of fixed fingers I I0 as fixed abutments for the partitions the movable leaves III begin to close, this being occasioned by engagement of arcuate actuating arm I28 by cam roller I38, shown in Fig. 11. Each leaf swings toward its associate abutment finger IIO, forcing a partition toward parallel, side by side engagement with that finger.

The orbital rotation and inward movement of the partition set-up head I08 tends to progress the carton longitudinally of chute I00. During said rotation of the set-up head sleeves H8, H1 contact cam surfaces I88, I38 giving longitudinal forward movement to plate I05, which movement is transmitted through arms I and I48 to the diagonally extending arm I50. The movement of arm I50 is in turn transmitted to arm ISI (see Fig. 13) and its associated parts including arm I54, which action starts the bottom erecting blade I" on the other side of the carton in motion in a direction longitudinally of the machine. The bell cranks I55, I80 assure line motion of the blade paralleling that of the carton by keeping its forward, notched edge parallel to the line of carton travel.

When the set-up head reaches approximately its point of maximum inward stroke the carton transverse partitions will have been forced into parallel relation between fingers H0 and leaves III of the head. This is occasioned by the fact that head I08 has a somewhat greater transverse or inward component in its orbital travel than the inward throw of plate I35, due in turn to the design of cams I38, I38 along which eccentric sleeves II 8, II! roll. Hence cam roller I38 engages arcuate actuating arm I28 to swing the latter counterclockwise at approximately the point of maximum inward travel of head I08. As a result, leaves I II are actuated to clamp the carton partitions against fingers IIO. At this time the lug I6 which advanced the carton into position opposite the head I08 will have advanced downward toward sprocket I8 sufficiently to engage arm I88 (see Fig. 14), forcing it rearwardly and disengaging hook I88 from its restraining relation to clutch lug I83 on plate I82. The steel and fibre disks I82, I84, respectively, of the clutch have constant, face to face, frictional, slip clutch engagement whereby disk I84 will turn without undue drag when plate I82 is restrained by hook I88. but will rotate plate I82 when hook I88 is disengaged. During the release period, when hook I88 has been disengaged, lug I8 will pass lever I88 and the hook will return to its normal position under tension of spring I81, reengaging lug I83 after one revolution of the latter and preventing further movement of shaft I18 until again disengaged in manner set forth above.

The single revolution of shaft I10 in the afore said release period is converted from arm I18 to a rapid forward and return reciprocatory movement of arcuate arm I", which is transmitted to bell crank I58; and the latter, with its associated parts including the, tandem-connected bell crank I80, gives a snap movement to blade I14 in an inward direction normal to the path of the carton, then a return movement outwardly. It will thus be seen that during a part of its operative cycle blade I14 is traveling in both a longitudinal and transverse direction. Maximum inward stroke of the partition set-up head I88 and the bottom and longitudinal partition erecting blade I14 occur at approximately the same time, at which moment the transverse carton partitions are at right angles to the carton bottom, firmly held between fixed fingers III and the forwardly extended leaves III on the head I08, as described above. The inner face edge of opposed blade I14 thus medially contacts the portion of the carton forming the bottom and longitudinal partition thereof, forcing it into secure locking engagement with the hooks on the transverse partitions, substantially as shown in Fig. 16.

Once the transverse partitions are in looking engagement with the bottom and longitudinal partition forming portion of the carton, the carton is progressed further forward under the impetus of the rotating head I08 and the longitudinally advancing, but outwardly retracting, blade I". During this short advance, lug I8 on chain I5 passes around sprocket I8 and advances over the end of guide I3 to re-engage the rear edge of the now set-up carton, whereupon it pushes the carton continuously until the latter is discharged from the machine, as chain II withdraws over the periphery of sprocket II.

From the foregoing it is apparent that I have provided a carton set-up machine of materially improved speed and effectiveness in operation. The cartons are moved in a single, relatively short, straight line path from the magazine II, through chutes 81, 88 wherein initial erection to box-like outline is performed and into the chute I00 in which the partitions of the carton are erected and operatively engaged. Likelihood of snagging, clogging and destruction of the articles is reduced to a minimum by this arrangement. The orbital, composite, longitudinal and lateral movements of the head I08 and partition engaging plate I" contribute substantially to overall smoothness and speed of operation, the cartons being practically unhalted in their longitudinal travel during operation by these components and being forwarded thereby during the portion of the cycle when the lugs I8 are disengaged from the carton.

The machine is rendered unfailing in its operation by reason of the positive control of the carton throughout the travel therethrough, i. e. by the positive engagement by the magazine feed dog 20, the magazine feed rollers 50, 4| and 8|, 42 and the advancing chain lugs I0. The cover restraining pocket 84, the forming chutes 81, 88 or I08, and in particular the side restraining lip I03 of the latter, all act similarly to engage and control the carton continuously in its travel, thereby eliminating the jamming, tearing, etc., which are so common in present-day machines.

While I have illustrated and described an operative and practical machine in the foregoing specification, I am aware that those skilled in the art will readily envision modifications there- 13' of characterized by the advantages to which I have referred; therefore I desire that the invention be construed sufllciently broadly to include any such modifications, to the extent that they fall within the scope of the appended claims.
